What each empire covers
- MGM Rewards: MGM Grand, Bellagio, Aria, Cosmopolitan, Luxor, Mandalay Bay
- Caesars Rewards: Caesars Palace, Horseshoe, Paris, Harrah's, Flamingo, LINQ
Earning
Both award points on resort spend (dining, spa, retail) and tier credits on casino play. MGM's tiers reward how often you stay; Caesars has historically awarded comps at a lower threshold.
The perks that matter
- Resort fee waiver: top tiers at both empires erase the $50-55 fee — worth as much as $300 across a five-night stay
- Free parking: both hand most mid-tier cardholders self-parking
- Show comps: Caesars flows faster; MGM converts into more dining flexibility
Our 2026 verdict
Light players: join both — they are free — and let each trip's booking pick the program you climb. Casino-first travelers do better at Caesars for the early comps; visitors who spend on spa, dining and suites extract more from MGM.
